前回よりも強くなる。 ジムでこの意識を持てないと、今日のトレーニングはなんとなくで終わってしまいます。 Deltaは、同じ種目の「前回」と「今日」を比べることをコンセプトにした筋トレ記録アプリです。 できること: ・前回の重量と回数を自動で引き継ぎ。入力は数字を少し直すだけ ・次に挙げる重量を提案 ・毎回の種目が決まっている人向けのテンプレート機能 ・推定1RM(今の実力で1回挙げられる重さの目安)の推移をグラフで表示 ・週ごとの総ボリュームと、部位ごとの偏りをチェック ・自己ベスト更新をトロフィーで表示 ・RPE / RIR は、使う人だけ記録可能 ジムで使いやすいように、数字は大きく、ボタンは片手で押しやすい位置に配置。 画面はシンプルで、余計な飾りはありません。 記録は端末内に保存されます。アカウント登録は不要です。 広告は買い切り(¥400)で非表示にできます。サブスクではありません。 日本語と英語に対応しています。 昨日の自分との差分を、今日の力に。 Deltaは、前回より強くなるための記録アプリです。

Verdict
The clearest difference is in-app purchases: Workout Map MuscleMap at none against Delta's 1. Workout Map MuscleMap also leads on ads (none vs shown). Delta's advantage is iOS requirement (15.1 vs 17.0). On price, update cadence and device support there is nothing between them.
